where is the outbox?

my messages are made to send after 3 minutes, and unfortuntaly usually within 30 seconds of sending a message i decide i want to alter something, but i see no outbox folder.

so what i have been doing to get the message is turning off my internet then the outbox message shows up and i can alter it.

is there a way of always showing the outbox message or it only works when the thing is offline?

Enable showing of Local or Smart folders - then the Outbox will be still visible.
